Procedural extraction.
Recent advances in machine reading comprehension, textual entailment [1]} and relation extraction [2]} shows the contemporary NLP models have the capability of capturing causal relations in some degree. However, it is still an open problem to extract procedural information from text. There were some attempts to extract similar procedural information on well-structured instructional text from how-to community. [3]} codifyhowto treated procedural extraction as a relation extraction problem on sentence pair extracted by pattern matching. They used OpenIE for pattern extraction and hierarchical LSTM to classify relation labels of sentence pairs.
